I doubt it really counts, but for the record...
Tomorrow I am running my Vampire game which takes place in summer of 2001 and I'll be playing a game based on the Dies the Fire book series, which takes place in Spring of 1998.

So that's kind of like pretending to be a time traveller. Though not as much as some of the other players who keep metagaming with info about what happens next in the timeline.

Thanks, Narf. Now I've got this weird conspiracy theory in my head, where some shadowy Illuminati-style organization has been using movies and television, influencing the human race for decades to believe that when you're defusing the bomb, it's never the red wire, so when the prophesied hero tries to defuse the doomsday device he cuts the green wire and kills everyone.
